18 Be like the grasshopper and make night musical. Nightly wash your bed and water your couch with your tears. Watch and be like the sparrow alone upon the housetop. Sing with the spirit, but sing with the understanding also. And let your song be that of the psalmist: “Bless the Lord, O my soul; and forget not all his benefits; who forgives all your iniquities; who heals all your diseases; who redeems your life from destruction.” Can we, any of us, honestly make his words our own: “I have eaten ashes like bread and mingled my drink with weeping?” Yet, should we not weep and groan when the serpent invites us, as he invited our first parents, to eat forbidden fruit, and when after expelling us from the paradise of virginity he desires to clothe us with mantles of skins such as that which Elijah, on his return to paradise, left behind him on earth? Say to yourself: “What have I to do with the pleasures of sense that so soon come to an end?
What have I to do with the song of the sirens so sweet and so fatal to those who hear it?” I would not have you subject to that sentence whereby condemnation has been passed upon mankind. When God says to Eve, “In pain and in sorrow you shall bring forth children,” say to yourself, “That is a law for a married woman, not for me.” And when He continues, “Your desire shall be to your husband,” say again: “Let her desire be to her husband who has not Christ for her spouse.” And when, last of all, He says, “You shall surely die,” once more, say, “Marriage indeed must end in death; but the life on which I have resolved is independent of sex. Let those who are wives keep the place and the time that properly belong to them. For me, virginity is consecrated in the persons of Mary and of Christ.”
